니 내 누군지 아니? 나 하얼빈 장첸이야! - 장이수

This meme began to gain popularity around May 2022, coinciding with the release of the movie <The Roundup>. The lines delivered by the returning character Jang Isu garnered immense popularity and spread widely online through various parodies.

"Do you know who I am? I'm Harbin Jang Chen!" is a line from the movie <The Roundup>, spoken by Jang Isu (played by Park Ji-hwan) as he bluffs and boasts to the villain Kang Hae-sang (played by Son Suk-ku). The humor stems from Jang Isu, who is not actually Jang Chen, attempting to intimidate by invoking the name of the powerful former villain, Jang Chen. This meme is primarily used when someone displays exaggerated confidence or bravado beyond their actual capabilities, or in situations where they try to intimidate others but come across as clumsy and comical.

The <The Outlaws> series is widely loved across all generations, and the character Jang Isu, in particular, is popular as a 'scene-stealer' and 'comic relief' in the series. Therefore, this meme is familiarly used by men and women of all generations who have watched the movie.

• When playfully boasting among close friends: "Hey, do you know who I am? I'm Harbin Jang Chen!"
• When confidently declaring one's ability to accomplish something, adding humor: "This project, do you know who I am? I'm Harbin Jang Chen! I'll get it all done!"
• It is also used self-deprecatingly in games or similar situations when trying to psychologically pressure an opponent, but lacking actual skill.

This meme is a line from a movie, and the original Korean contains somewhat crude and informal language. Therefore, it is advisable to refrain from using it in formal settings or situations requiring politeness. It is appropriate to use it humorously among close acquaintances, and one should carefully consider the situation and atmosphere to avoid offending others.

The Korean phrase "니 내 누군지 아니? 나 하얼빈 장첸이야! - 장이수" is pronounced as: "Nee na-eh noo-goon-jee ah-nee? Nah Hahr-bin Jahng Chen-ee-yah! - Jahng Ee-soo"
